Can Saline Breast Implants Affect my Asthma?

The answer is nope.

On looking at some of the other answers here, I would endorse the suggestion that you consider cohesive gel filled implants if you are comfortable to have implants at all.  They're simply much better than saline.  In Australia, we've been using them since 1997 and the long term results are superior in the longevity of the implant and the naturalness of the feel of the breast provided you don't get a capsular contracture (the risk of which is the same in saline or gel implants).

Despite many studies showing that breast implants are not an unsafe thing to have done from your health point of view, its my advice that if you feel a sense of discomfort about having breast implants put in, then simply don't.  Life is too short to add a possible stress to it.

Good luck! 

There is no demonstrated relationships between breast implants and asthma. It will be important to have you asthma under control prior to the surgery, and I routinely have my asthma patients bring their inhalers to the surgery center as some inhalers are very helpful in keeping the airways relaxed during surgery.

It is almost impossible to avoid exposure to silicone in everyday life. Two in particular Dimethicone and Dimethylpolysiloxane are used in everything from cosmetics, shampoos, conditioners and even as a food additive. Silicone is even used for the valves in inhaler spacers.
